摘要
广州地铁二号线磨碟沙站基坑围护结构的设计由原来的钢支撑加钻孔桩改为LXK工法锚杆加钻孔桩,本文对这两个方案进行了对比。并根据场地条件的不同设计出不同的锚杆:旋喷水泥土锚杆、搅拌水泥土锚杆以及扩大头伞型地锚,该工程试验和监测结果表明,采用该支护体系技术合理、安全可靠、节约资金。
The primary supporting structure design of steel bracing and bored piles was changed into LXK constructing method anchor and bored piles in Modiesa station excavation of Guang Zhou Metro II. Two designs are compared in this paper. According to the different fields, different anchors are designed including: drilling jet grouting anchor, mixing concrete earth anchor and reaming earth anchor. The test and supervision results show that the application of such supporting system is technically reasonable, safe and reliable, and economical of cost.
